Question

A number when added to its half 72.find the number

Answer 1

Let the number be x.
Therefore , According to the question when we form equation , we get -

x + x/2 = 72
or, (2x+x)/2 = 72
or, 3x/2 = 72
or, 3x = 144
or, x = 144/3
or, x = 48

Proof -
48+(48/2) = 48+24=72.

Answer- 48 when added to its half gives 72.

Answer 2

Let us consider the unkown number as x

72= x + x/2
72= 2x/2 + x/2
72 = 3x/2
72 ÷ 3 = x/2
24 × 2 = x
48 = x

If 48 is added to its half the result will be 72
48+48/2
= 48+24=72.
